Safe journeys through the high mountains
The project was to reroute a 1.3 km stretch of the L 197 Arlberg pass road, which was at risk of rock falls and carriageway subsidence. To enable road users to use the route more safely, TEERAG-ASDAG constructed five supporting walls (1,700m³, up to 11m in height) for the section most at risk, in the steep alpine terrain above Stuben.
- Rock removed soil class 6-7: 55,000m³
- Specially coated surfaces 10-20cm: 1,500m²
- IBO anchors: 3,200 m
- Permanent ground anchors 950KN: 600m
- Faced brickwork: 1,600 m²
- Granite hard shoulder, 15/24 ROA1: 1,900m
- Frost layer: 15,100 m³
